Hopup, Buckings and Barrel Testing and Troubleshooting

I’ve posted a video that demonstrates some of the tests you should do with your hopup, bucking and barrel to troubleshoot BB feeding problems. The video shows the BB drop test, BB push through test, and how to test for air seal on the PolarStar Fusion Engine.

Happy Airsofting!

Here’s a follow-up video showing how to sand down bucking lips.
